we provide an abutment on the gun cradle for part of the lifting tray and we so construct this tray that, when it comes against thesaid abutment during the raising of the tray, the latter will be swung about a trans verse axis into a position in which the proectlle thereon can be displaced endw-ise' on i to awaiting tray mounted on the cradle. The said abutment is preferably constituted by the forward and, of' this waiting tray which serves as an intermediate platform,

or bridge piece between the lifting tray and the aforesaid swing-ingtray on the cradle. This arrangement enables the pro ectlle to slide automatically from the lift' ing' tray on' to 'thczwaiting tray, and thence to the aforesaid swinging tray, when the j We .may employ .a stop device which so constructed and arranged that it will'prep p venta pro ectlle from being delivered to the According to the present inventlon there waitlng tray from. he lifting tray when is provided beneath the gun platform, .a

placed to its inoperative position when the swinging tray moves away fromthe waiting tray. In conjunction with the said alternative construction a second stop device may be arranged on the Waiting tray to prevent.

the projectile from passing out of it in'ja 'rearward direction in the event of the swinging tray not belng opposite the waitp ing tray, this stop device being automatically moved to its inoperative position when the swinging tray comes opposite the waiting tray, so as to enablethc projectile to thenpass freely into the swinging tray. *We.

may furthermore provide'on each side of the:

waiting tray a spring controlled safety pawl adapted to engage withthe forward portion "of the projectile, thesepawls permitting the projectile to slide base first on toand from I the tray but preventing the projectile from;

' sliding out nose first in the eventof the.

ship that carries the mounting rolling to I suchan extentas would cause such movefor In order that the saidinventlon'may bef: clearly understood and readily -carried into effect, we will now describe the same more fully with reference to-the accompanying Figs. 3 and 4 are sections takenapproxr" mately on the lines 3, 3 and 4, of Fig, 1

B B are straight throughonly a portion of their length; the up-per portions being curved as shown by Fig. 1 to form Cam tracks forthe rollers C C so as to cause thelifting tray C to be tilted aboutthe axis of the I rollers C C into 'the position-shownby chain lines at the upper part of Fig. 1 to cause the projectile to slide base foremost on to the waiting tray E. j As shown' b-y Figs. 9, 10 and 11 the trunnions carrying the rollers C C have loosely mounted onthem a stirrup piece (3 to the upper ends of which the cables (3*, O are connected and-to the lower'endof which a cable C leading to a drum C (Figs. land 3) is connected: The waiting tray E has a stop-piece e to prevent the projectile from'sliding oil the tray and is formed with a gap e to enable the loading number to place his hand beneath the projectile in order to lift it from the waiting. tray and place it on the swinging trayF.

The said waiting tray is also provided with i a stop device G (see Fig. 8) in the form of V a bolt connected to a bell crank lever G" whose rear arm is adapted to project above the surface of the tray so that when aprojectile passes on to the tray the said lever will be operated thereby to 'cause'the bolt to project above the surface of the tray and so prevent a projectile from being delivered 'to' the tray from the lifting tra'yso long the projectileremains on-t-he waiting tray,

When the latter projectile is'removed .the

bolt G is returned to'itsinoperativegpositionby a handle G* on the lever-G In the construction shown by Figs. 12 to 15 the casing B is curved instead of being" straight and the waiting tray E instead of being on the mounting is on the cradle. The lifting tray has two sets of rollers C C and C C ofwhich the. latter engage in guides B B constituted by two sets ofangle: irons 6, Z), andfb, b; the rollers CKC? bearupon the front surfaces of the angle irons I), b; The waiting. tray'E is formed with two forward extensions'E", E havingrurved re-' cesses e 6?? in their undersurfaces and the cable C is'connectedfltothe lifting tray in such amanner that when the rollers 6 ,0? come. into contact with therecesses e 6" duringthe' last part of the upward movement of the lifting tray. a continued pullon the cable. 0* will cause the lifting tray to be rocked about the axis of the rollers C G into aposition in line with the waiting. tray E, ithis'positio'n. being determined by the engagement of therear end of the lifting tray in a recess E in the forward end ofthe wait'ing tray '15. Durin 'the rocking of the lifting tray therollers C are moved out of'cont'actfwith the angle'irons b, b. It

will-be observedthat the waiting tray E constitutes 'a bridge piece between the lifting tray C and the swinging'tray F so that if" tally-or is at only Very small angles of ele vat-ion the-projectile will have to b64118 placed axiallyby hand from the lifting-tray to the swinging tray; x Rgferring to'Figs. 16 to 21, G'is the stop device for preventing a projectile fronr-being delivered from the lifting tray C to the I waitingtray E when another projectile'ison the waiting tray or is on the swinging tray F with the latter opposite the waitingtray,
